Mr. Meyer is shocked that someone received such a low score on the exam. When he checks the grade sheet on the computer, he discovers that the low score belongs to one of his best students in math. He wonders what happened. What do you think happened? 7./ Below are two box plots that represent the distribution of the weights in pounds of 40 women and 20 men. Women n=40 50 150 200 300 Weight a. List at least cight questions that can be answered by looking at the two box plots above, and provide answers for your questions. Try to avoid asking the same questions for each box plot-e.g., do not list both "What is the median weight of the males?" and "What is the median weight of the females? b. List at least three questions that cannot be answered by examining these two box plots. c. What important points do you think the graph makes? d. If we assume that outliers on the right of the box-and-whiskers plots indicate overweight individuals, would it be correct to state that, in general, there are three times as many overweight women as men? Why or why not? Suppose we grouped all the weights of the men and women from Learning Exercise 7 into a single data set and constructed a box plot. Draw a picture of what you think that plot would look like, and explain why it looks the way it does. Examine the following histograms and explain why or why not each could be a histogram that best fits the weights data of the 20 males in Learning Exercise 7: 8. 9. b. 4. 100 150 200 250 300 Weight (in pounds) 100 150 200 250 300 Weight (in pounds) continueExplanation / Answer
a)
We have following questions that can be deduced from the box plot of the distribution of weights of two groups,40 women and 20 men.
1.What is the median weight of each group?
2. Which group has a greater number of outliers?
3. What does a large number of outliers tell us about data?
4. Which group has larger interquartile range?
5. What does larger interquartile range tell us about data?
6. Which group have whiskers smaller than the other?
7. What do smaller or larger whiskers tell us?
8. What is the difference between the medians of two groups and what does it signify?
b)
1. What is the mean of each group?
2. What is the variance of each group?
3. What is the distribution of data?
c) The main points we get from this box plot are
1. The median weight of women is lower than the median weight of men.
2. The upper quartile of women is lower than the lower quartile of men.
3. The median weight of women is equal to the weight of the lower extreme weight of men.
4 The interquartile range of men is larger than the interquartile range of women.
5. We have more outliers in case of women than in men.
6. The fourth quartile of the weight of men is bunched together while 4th quartile of women is spread out.
d) No this is not correct interpretation as its just a small sample, and it does not mean that all the population will have three times overweight women than men.
